摘要： A vehicle light which uses a laser light source device and has a shorter dimension in an optical axis direction than conventional vehicle lights. The vehicle light comprises a laser light source device and an optical system configured so as to form a predetermined light distribution pattern. The laser light source device includes: a cylindrical light-guiding part having a diffusing surface set in a region other than a light-introducing surface; a phosphor arranged in a light-emitting region on an outer circumferential surface of the light-guiding part; a reflective film arranged in a region of the light-guiding part other than the light-introducing surface and the light-emitting region; and a laser light source that outputs a laser beam which is introduced into the light-guiding part from the light-introducing surface and enters the phosphor. The light-guiding part and the laser light source are arranged adjacent to each other.

摘要： A wavelength conversion structure includes a light guide formed of a light-transmissive member having a laser light incident port that allows the laser light to be introduced and a phosphor-containing layer that covers at least part of the surface of the light guide. The light guide has a light diffusing structure having asperities and a light reflecting film. The asperities are formed over the surface of the light guide except a laser light incident surface having the laser light incident port. The light reflecting film is formed over the surface of the light guide along the asperities except the laser light incident port and the portion covered with the phosphor-containing layer.

摘要： A wavelength converting member radiates light having a wavelength different from that of laser light introduced into the wavelength converting member. The wavelength converting member has a phosphor layer that contains a phosphor therein. The phosphor layer has a laser light incidence surface capable of receiving the laser light. The wavelength converting member also has a high-refractive layer that is bonded to an opposite surface of the phosphor layer to the laser light incidence surface thereof. A refractive index of the high-refractive layer is higher than a refractive index of the phosphor layer. The high-refractive layer has concaves on at least either the bonding surface where the high-refractive layer is bonded to the phosphor layer or a light extraction surface that is opposite the bonding surface.

摘要： A nitride semiconductor light emitting device is formed by: forming a resist pattern on a first nitride semiconductor layer formed on a substrate, the resist pattern having a region whose inclination angle relative to a substrate surface changes smoothly as viewed in a cross section perpendicular to the substrate surface; etching the substrate by using the resist pattern as a mask to transfer the resist pattern to the first nitride semiconductor layer; and forming an light emitting layer on the patterned first nitride semiconductor layer. The nitride semiconductor light emitting device can emit near-white light or have a wavelength range generally equivalent to or near visible light range.
